FGG180-12 best sealed deep cycle gel battery 12v 180ah

Gel Battery 12V 180AH | Dimension: 532x206x215x219mm

SKU: FGG180-12 Category:

GRANKIA FGG 180-12 best sealed deep cycle gel battery 12v 180ah is manufactured with special separators and silica gel immobilizing the electrolyte inside the battery. The proven silica gel technology can improve battery cycle life and performance at wider temperature range.

This deep cycle gel battery 12v 180ah is perfect for critical systems due to its ability to withstand more than 750 charge/discharge cycles at 50% DOD. It is special lead calcium alloy composition, which improves corrosion resistance of grids and increases the battery service life.

The deep cycle gel battery consists of a gel rather than a liquid, so no maintenance is required to keep the battery working properly. The gel cell deep cycle battery is using advanced valve-regulated technology with a narrow operating pressure range. It is equipped with explosion-proof and acid filters to avoid acid leakage and frequent maintenance.

Deep Cycle Gel Battery Features

  • High quality fumed silica gel electrolyte: no flow, no leakage, all parts of the plate in uniform reaction.
  • Tight assembly technology: high efficiency discharge performance.
  • Gel electrolyte, battery with good heat dissipation ability, battery can work at lower and higher temperature.
  • High purity raw material: low self discharge rate.
  • Oxygen recombination technology: safe and eco-friendly.
  • Excellent deep discharge recovery: Proprietary plate composition and patented gel electrolyte ensures excellent recovery capability after excessive deep discharge. This means that GEL batteries can discharge more and still be recharged like new.

AGM Gel Battery FAQ

  1. Does a gel battery last longer than an acid battery?

    A high-quality 12V gel battery that is similarly cared for and regularly kept at a high charge will last over a decade and can last upwards of two decades.

  2. What is the advantage of a gel battery?

    Best suited for Deep cycle applications and their life is generally in the 500 to 5000 cycles range. Maintenance free. Spill proof. Minimal corrosion therefore compatible with sensitive electronic equipment.

  3. Do gel batteries last longer than AGM?

    AGM batteries are comparably cheaper than Gel batteries, but they present a longer life span and offer bigger bursts of amps when needed.
